13. Urena lobata Linn. 
Great Coco ; in one spot only, in interior of island. 
A cosmopolitan tropical weed, introduction in this case may be 
attributed to bird agency. It hardly seemed to be indigenous as there 
were where it was gathered only a few plants. Yet human agency 
appears impossible : the species is not present at the north-east of Great

Little Coco. 
Cosmopolitan in the tropics.
